I can't find anywhere else to post this question, so here goes. Since my last update of Firefox, I am getting this pop up error message when browsing the internet. Not with every attempt to go to a new page or site, but periodically:

Secure Connection Failed

Beta.sling.com:443 uses an invalid security certificate.

The certificate is only valid for the following names: A248.e.akamai.net, *.akamaihd.net

(Error code:ssl_erro_bad_cert_domain)

This could be a problem with the server’s configuration or it could be someone trying to impersonate the server.

If you have connected to this server successfully in the past the error may be temporary and you can try again later.

Is Slingmedia going to update their software, ever? I do not want to have to go back to an earlier version of Firefox.

I too have been getting this error. I found an old program from slingbox and uninstalled it.

I clicked on control panel and then program and features, using view by small icons. I uninstalled all slingbox related programs. I then uninstalled all slingbox plugins/extentions in firefox. I went back to slingbox.com and let it do its thing. The program and feature screen is clean. I do not know if this is the issue or not, as I have only seen this request and error message a few times the past few weeks. I am not sure how to trigger it. I hope this cleaned it up. I do not like programs going out to the net like this.

I had replied to this and it appears to have been deleted. Maybe because I included a link to a thread on the Mozilla board where someone posted this problem and 30+ people have said that they have same problem?

Anyway let me try again. This is not a Firefox version issue. The link you included simply says version 5 or above. I am running version 7. This is a real problem that needs to be investigated, not written off as a user error. I would suggest that you send this to someone who can actually investigate it, since it is clearly a problem that needs to be resolved.

This is not an issue while I am using slingbox or watching slingbox.com. Your software somewhere is making a call out to the net when I am not using the softeware. Please see screenshot on other post. Please read the other posts as well.

Yeah, I have seen this error a couple times while viewing my slingbox through a Firefox browser window, after Firefox did one of their almost-automatic updates. If many folks have reported similar errors to Firefox forums, I expect that the Firefox folks will fix the problem at their end shortly.

Try disabling SlingAgentService in services.msc. I think this is because they have not updated their Windows Slingplayer for quite some time and it's quite possible this "phone home" service is calling on outdated cert. They have been utilizing all their efforts on the web browser viewer.

I noticed this was happening on all my PC's except one. The one thing that was different was the service was disabled.

Ok. After this **** pop-up got me oonce again. I went directly to the site: https://beta.sling.com:443/. Of course Firefox spit it back at me that the cert was bad, but I added an exception, and I can now see the cert in my cert list. The issue date is 9/1/11. Now I shouldn't get those annoying alerts anymore. This should fix the pop-up problem. Now I have to figure out what is calling this cert. It has to be the plugin. To be continued...

Thanks for figuring this out. I had considered it strange that there wasn't a comparable option to accept the certificate on the error we were receiving. Hopefully this will cause the popup to no longer appear. However, it doesn't really fix the underlying problem and Sling really needs to do something about it.

FWIW, I'm also still getting this error on a daily basis. And I haven't been accessing my Slingbox at all. When that alert pops up, Firefox stops working and won't even resolve hostnames. I have to quit and relaunch Firefox to get it working again.

Thanks, Bill... I did that and got this error but perhaps it's because there was that trailing slash in the URL. I'll try adding the exception with the URL without that slash and see how that goes. Thanks again.

Invalid URL

The requested URL "/", is invalid.

Reference #9.aae1fc7d.1318470573.a2801404

The connection was reset

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.If you are unable to load any pages, check your computer's network connection.If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

(Try Again)

Oh well...

There's obviously an issue with Slingbox's software. I wish they'd come up with a fix.

In firefox this is normal. There is no site published at that url. You need to click left of the address bar and add an exception. Highlighted in yellow.

By the way, this really is not a Sling problem. With the latest hacks of Certificate Authorities Microsoft and Mozilla have hunkered down on bad certs with patches that pick them out and alert you. I am assuming that since Sling has not done development of Windows SlingPlayer since 2008, this is left over from the player. Just a hunch.

While I reported that I had also seen this error message on my Firefox browser back in September, I no longer see it since my Firefox has gone through several updates of its own (now Version 8.x?) and the Slingbox plug-in has also gone through a couple of its own mandated updates since September.
